In 1889, L-Lysine was first isolated from the protein casein by the German biological chemist Ferdinand Heinrich Edmund Drechsel. In 1902, two other German chemists discovered L-Lysine's chemical structure by synthesizing it. This amino acid is used in the synthesis of proteins and is considered an essential amino acid, as our bodies are unable to synthesize it on their own. L-Lysine can be found in foods such as fish, beef, chicken, cheese, soybeans, peas, and lentils just to name a few foods. As one of the 9 essential amino acids our bodies need, we rely heavily on acquiring the required amounts by the food we eat, however, with nutrient depletion in the soil a very real problem, this isn't always possible anymore. It is becoming more and more mainstream to supplement this amino acid through capsule or pill form. Superior Labs provides one of the most bioavailable forms of L-Lysine sold today. We use only the highest quality ingredients, combined with the most innovative scientific research to bring you the most effective and potent products on the market.
